Large Scale Overdensity of Lyman Break Galaxies Around the z=6.3 Ultraluminous Quasar J0100+2802

Posted by dbos Peking

Kavli Affiliate: Linhua Jiang | First 5 Authors: Maria Pudoka, Feige Wang, Xiaohui Fan, Jinyi Yang, Jaclyn Champagne | Summary: We study the environment of the z=6.33 ultraluminous quasar SDSS J010013.02+280225.8 (J0100) to understand its association with large-scale structure. Theoretical models propose high-redshift quasars as markers of galaxy overdensities residing in the most massive dark […]

Feedback mechanisms stopping the star formation in a pair of massive galaxies in the early Universe

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Pablo G. Pérez-González, Francesco D`Eugenio, Bruno Rodríguez del Pino, Hannah Übler, Roberto Maiolino | Summary: Feedback is the key physical mechanism regulating galaxy formation. Stars in galaxies form when baryons radiatively cool down and fall into gravitational wells. Eventually, star formation quenches as gas is depleted and/or […]

Copas-Heckman-type sensitivity analysis for publication bias in rare-event meta-analysis under the framework of the generalized linear mixed model

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Taojun Hu, Xiao-Hua Zhou, Satoshi Hattori, | Summary: Publication bias (PB) is one of the serious issues in meta-analysis. Many existing methods dealing with PB are based on the normal-normal (NN) random-effects model assuming normal models in both the within-study and the between-study levels. For […]

Understanding Server-Assisted Federated Learning in the Presence of Incomplete Client Participation

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Haibo Yang, Peiwen Qiu, Prashant Khanduri, Minghong Fang, Jia Liu | Summary: Existing works in federated learning (FL) often assume an ideal system with either full client or uniformly distributed client participation. However, in practice, it has been observed that some clients may never participate in FL […]

Modulation of aggression by social novelty recognition memory in the hippocampal CA2 region

Posted by dbos Columbia

Kavli Affiliate: Steven Siegelbaum | Authors: Andres Villegas and Steven A Siegelbaum | Summary: The dorsal CA2 subregion (dCA2) of the hippocampus exerts a critical role in social novelty recognition (SNR) memory and in the promotion of social aggression. Whether the social aggression and SNR memory functions of dCA2 are related or represent independent processes […]
